This is a ground chicken burger topped with mole poblano sauce — the kind of sauce that usually takes all day, but here gets done with jarred mole paste, chicken broth, and a handful of dark chocolate chips. It’s a genuinely different burger that’s worth making on a weeknight because the sauce comes together in about ten minutes and the patties are straightforward. The cotija on top is not decorative; the salt cuts right through the richness of the mole.
The short version of why this works
Two things make or break this burger. First, use ground chicken that includes dark meat — packages labeled “ground chicken” at most grocery stores are a blend, and that fat is what keeps the patty from turning into a dry puck at 165°F. Pure ground chicken breast will dry out fast; if that’s all you have, work a tablespoon of olive oil into the mix before forming patties. Second, the mole sauce needs a real simmer — at least five minutes after you add the chocolate chips — so the paste fully dissolves and the chocolate loses its raw edge. Rush it and the sauce tastes gritty and a little bitter. Give it time and it goes glossy and smooth.
Common problems and fixes
- Patties fall apart on the grill: Ground chicken has less binding fat than beef. Chill formed patties in the fridge for 20–30 minutes before cooking — cold fat holds the shape. Skip the egg in the mix; it makes the patty mushy and doesn’t actually help it hold together on a hot surface.
- Mole sauce is too thick and clumps: Add chicken broth a splash at a time and whisk constantly over medium heat. Different brands of mole paste vary in density, so treat the broth quantity in the recipe as a starting point, not a fixed number.
- Can’t find cotija: Feta works well — similar salt level and crumble. Queso fresco is milder but still good. In a pinch, a sharp dry parmesan shaved thin does the job.
- Mole paste is expensive or unavailable locally: Check the international aisle rather than the Mexican food section — it’s often stocked there. Online it’s cheaper per ounce in larger tins. A 70%-cocoa dark chocolate bar broken up substitutes fine for the chocolate chips; just chop it roughly first.
- Bun gets soggy fast from the sauce: Toast the bun cut-side down in a dry pan until it’s genuinely golden, not just warm. A toasted bun holds up to the sauce for the full meal instead of collapsing halfway through.
Keeping and reheating
Cooked chicken patties keep in an airtight container in the fridge for up to three days. Store the mole sauce separately — it refrigerates well for four to five days and actually tastes better on day two once the flavors settle. To reheat a patty, a covered skillet over medium-low with a splash of water for two to three minutes works better than a microwave, which toughens ground chicken quickly. The sauce reheats in a small saucepan over low heat; add a little broth if it’s thickened too much in the fridge. Raw formed patties can be frozen on a parchment-lined tray, then transferred to a zip bag, for up to two months — thaw overnight in the fridge before cooking and make sure they reach 165°F internal temperature.
Mole Poblano Chicken Burger
Ingredients
Burger Patties
- 1 lb ground chicken Preferably with some dark meat for juicier patties
- 1 tsp garlic powder or 1 clove fresh garlic finely minced
- ½ tsp salt
- ¼ tsp black pepper
- 2 tbsp vegetable oil For brushing grill or pan
Mole Sauce
- 1 tbsp vegetable oil
- ½ cup mole poblano paste Look for authentic mole poblano paste from a specialty store
- 1 cup chicken broth Low-sodium preferred
- 1 tbsp dark chocolate chips 70% cocoa or higher for authenticity
Burger Assembly
- 4 medium burger buns Lightly toasted
- 4 pcs lettuce leaves Green leaf or romaine
- 4 slices tomato Fresh, ripe slices
- 4 tbsp crumbled cotija cheese Optional, or use feta as a substitute
Instructions
- Prepare the Burger Patties: In a mixing bowl, combine ground chicken, garlic powder, salt, and black pepper. Mix gently until well incorporated, but do not overwork. Shape into four equal patties about 2 cm (3/4 inch) thick.
- Make the Mole Sauce: Heat 1 tablespoon of vegetable oil in a saucepan over medium heat. Stir in the mole poblano paste and gradually add the chicken broth, whisking to dissolve the paste. Once smooth, add the dark chocolate chips, allowing them to melt completely. Simmer for 5–7 minutes until the sauce thickens slightly.
- Grill or Pan-Sear the Patties: Preheat your grill or skillet to medium-high heat (around 200°C/400°F). Lightly brush with vegetable oil. Cook the patties for about 4–5 minutes per side, until they develop a golden crust. Ensure the internal temperature reaches 74°C (165°F) for fully cooked chicken.
- Assemble the Burgers: Toast the burger buns if desired. Place a lettuce leaf on the bottom bun, followed by a hot chicken patty. Spoon a generous amount of mole sauce over the patty. Top with a slice of tomato and crumbled cotija cheese. Finish with the top bun.
Notes
- For those who prefer a thicker sauce, simmer an extra 2–3 minutes or until it reaches desired consistency.
- Add avocado or pickled jalapeños for a fresh, spicy twist.
- If you can’t find cotija cheese, feta or queso fresco will work well.
- Plate each burger open-faced to showcase the richly colored mole sauce. Garnish the plate with fresh cilantro leaves or a lime wedge to brighten the flavors.
- Serve with sweet potato fries or a simple side salad dressed with a citrus vinaigrette to balance the burger’s rich flavors.
- The mole sauce in this recipe pays homage to traditional Mexican mole poblano, which often includes an array of chilies, nuts, seeds, and chocolate. By infusing these flavors into a chicken burger, you can experience a fusion of both comfort food and classic Mexican heritage.
- Prep the mole sauce in advance and store it in the refrigerator for up to 3 days. Warm before serving.
- For an authentic texture, grind roasted chilies and spices into your own mole paste, though it is more time-consuming.

Frequently asked questions
Can I use store-bought rotisserie chicken instead of making patties?
No — the recipe specifically uses ground chicken formed into patties, so rotisserie chicken won’t work as a direct swap here. If you want a shortcut, ground chicken from the store is already prepped and ready to season and shape.
What if I can’t find mole poblano paste — can I make it from scratch?
Scratch mole is a multi-hour project and not practical for a weeknight burger. A jarred or canned mole paste is the intended ingredient and gives you 90% of the flavor in a fraction of the time. Dona Maria and El Mexicano are two widely available brands in US grocery stores.
How do I know when the chicken patty is fully cooked without cutting it open?
Use an instant-read thermometer and pull the patty at 165°F internal — that’s the safe temperature for all ground poultry, no exceptions. Insert the thermometer into the side of the patty horizontally to reach the center.
Can I make the mole sauce ahead of time?
Yes, and it’s actually a good idea. The sauce keeps in the fridge for four to five days and the flavor improves overnight. Make it the day before and just reheat it gently while the patties cook.
What can I use instead of dark chocolate chips if I don’t have any?
Any dark chocolate with 70% cocoa or higher works — just chop a bar into small pieces so it melts evenly. Semi-sweet chocolate chips are a passable substitute in a pinch, though the sauce will be slightly sweeter.
